Title: Improvements relating to a photosensitive material
IPC: C23C18/16
Filed: 1965-03-18
Abstract: 1,092,607. Photo-sensitive materials. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 18, 1965 [March 21, 1964], No.11532/65. Heading G2C. A photo-sensitive material is produced by coating on a support at least the surface of which is water-impervious and electrically insulating, a non-crystalline layer comprising a photosensitive compound which on exposure to light forms a product which can release mercury and/ or silver from mercurous and/or silver compounds, a wetting agent and a compound which inhibits crystallization. This material may be imagewise exposed through the support which is transparent, treated with a soluble containing mercorous and/or silver salts to produce a latent mercury and/or silver image and then physically developing this image by using a solution containing a metal salt to produce the appropriate metal image. Alternatively, a mercury or silver image may be produced on development which is then electro-plated to give the desired copper, nickel or cobalt image. The specified photo-sensitive compounds are aromatic diazosulphonates and anthraquinone disulphonic acids. Specified crystallation inhibitors are dextrin, sorbitol, calcium lactate and lactic acid or the wetting agent. The surface of the paper or polymeric support may be rendered water-impervious necessary by coating it with wax, a cresol-formaldehyde resin or a butadiene/acrylonitrile copolymer before applying the light-sensitive solution. The support may be treated on both sides in this way and lightsensitive layers applied to both sides of waterimpermeable support so that a printed wiring pattern may be obtained on both sides of the support.

Title: Improved uranium mononitride composition and method of making
IPC: G21C3/62
Filed: 1965-03-19
Abstract: Uranium nitride having dispersed therein 20 to 56 mole per cent of discrete bodies of titanium nitride is made by reacting an alloy of uranium and 5-20% by weight of titanium with nitrogen under pressure in an electric arc.  The presence of titanium inhibits disproportionation of the uranium nitride, yields a stronger product, and enables the reaction with nitrogen to be carried out at a lower pressure e.g. 5 atmospheres.  The product is used as a nuclear fuel.

Abstract: 234,472. Muadorf, E. May 20, 1924, [Convention date]. Fulling.-In the fulling of fabrics while in the form of rope, the latter is wound so that, as shown in Fig. 3, the warp and weft threads both are inclined to the length of the rope, in which direction the material is moved during the washing &c. operations. To effect this helical winding of the material, the cloth from a roll c, Figs. 4 and 5, is wound obliquely round a board d and at the same time moved longitudinally along the board. The edges of the fabric are secured by sewing so as to prevent disarrangement during the washing &c.

Title: An improved method of and means for electro-magnetically recording acoustic signals
IPC: G11B5/00
Filed: 1931-04-22
Abstract: 377,276. Electromagnetic soundrecording apparatus. DAHMEN, K., 29, Dorotheenstrasse, Dusseldorf, Germany. April 22, 1931, No. 11913. [Class 40 (ii).] Comprises a method for the electromagnetic recording of sound in which a plurality of different sound records are superimposed upon each other by producing a pair of records of each signal simultaneously and causing predetermined wave-form variations of the mean recording intensity of one while varying the mean recording intensity of the other inversely to the first, different wave-form variations of mean intensity being allocated to the different pairs of records. The record carrier consists of two pre-magnetized steel bands 1 which move over guide rollers 2 at constant speed, and above the bands 1 are arranged two electromagnets 11, 12. The electromagnets 11, 12 are moved towards and away from the bands 1 by the operation of oppositely-disposed cams 9, 10 which are driven by a shaft 7 rotated by a pulley 8. A lead 22 of the recording circuit is connected to the coils 3, 4 of the electromagnets 11, 12 through two variable resistances 13, 14, the sliding contacts 15, 16 of which are relatively displaced by an angle of 180‹. The other end of the coils 3, 4 is connected to the lead 21 of the recording circuit. When a record is being made, the contacts 15, 16 are rotated uniformly by sheaves 17, 18, so that the current strengths in the coils 3, 4 will be varied to follow a wave-form curve, the variations of current in one coil being the exact inverse of that in the other coil. The total mean intensitv of the magnetic influence acting on the bands will be constant however. At the same time, the magnets 11, 12 are alternately moved towards and away from the bands 1 to cause further inverse variations of the magnetic intensity. By suitably choosing the speeds at which the cams 9, 10 and sliding contacts 15, 16 are rotated records may be produced which vary in mean recording intensity in accordance with curves having predetermined characteristics. Reproduction of each recording may then be effected by rotating the cams 9, 10 and sliding contacts 15, 16 at the same speeds as were employed during the recording of the particular signal to be reproduced, the magnets 11, 12 then serving as reproducing devices which feed a loud-speaker through an amplifier. It is stated that, in these circumstances, the other recordings carried by the bands 1 will not be reproduced to an extent sufficient to render the required reproduction confused.

Title: Improvements in Automatic Steam Traps.
Inventor: LOBET ALEXANDRE
IPC: F16T1/24
Filed: 1919-05-13
Abstract: 126,963. Lobet, A. July 9, 1917, [Convention date]. Steam-traps.-When the trap is not working, or is only under low pressure of steam, the spring 27 keeps the valve 6 and casing 13 raised, and air and condensation water entering at the port 2 can escape through the openings 9 to the outlet 4. As the pressure rises in the vessel 1, the casing 13 is forced downwards, thus closing the valve 6. Water accumulating, the float 24 rises and strikes the levers 19, 20 and opens the valve 16. Steam is thus admitted to the casing 13 above the loosely-fitting piston 25, and the casing again rises and the valve 6 opens. The water escapes and the float drops clear of the levers, allowing the valve 16 to close. The steam inside the casing 13 passes by the piston 25 and through the port 11 and passage 10 to the outlet 4. The pressure of steam again drives the valve 6 on to its seat, and the operations are repeated.

[Also in Group XVI] A pleated metal foil cap for bottles or the like has a long skirt of which the bottom end is formed radially outwards whereby the cap has a generally cylindrical portion 1 closed at one end and a radial flange portion 3 at the other end so that the cap will stand in a stable condition when supported on the flange portion. The cap may be used in a bottle capping machine, as shown in Figs. 2, 3, comprising a shoot 5 and smoothing and sealing heads 8, 24. Caps are fed down the shoot 5 to bottles conveyed past the lower end thereof. Rods 6 spaced from the surface of the shoot engage the flanges 3 of the caps and are slightly inturned at their lower ends so as to prevent the bottom cap from slipping off the shoot until it is engaged at R by the leading edge 7 of a bottle neck and thereby carried off the shoot. A gate 10 on the shoot obstructs the flow of caps and is opened to allow one cap at a time to pass to the lower end of the shoot by means of a lever 31 contacted by a bottle as it approaches the shoot. The bottle with a cap resting on top is moved under the smoothing head 8 which smoothes the flange down about the bottle neck, and then to the sealing head 24 which closes the cap firmly against the bottle neck by means of a sheath 25 internally expansible against the cap.
